Temu Order Not Delivered After Estimated Delivery Date

I placed an order on the Temu app on 10 October and, as of today, my package still has not been delivered. In the app it shows as “In transit” with CN Express, and the estimated delivery window was 17–28, but that time has already passed and I have not received anything. This order is urgent for me and the delay is causing me serious inconvenience. I have already emailed Temu support and contacted your customer service several times, speaking with different agents. Each time I am told that the issue will be solved, but nothing actually changes and the package still does not arrive. I also see that some credits or coupons were added because of the delay, but these do not solve my problem because I needed the items themselves on time. At this point, I no longer want to wait for this shipment. I kindly request a full refund for this delayed order, including any shipping costs, and for the order to be cancelled if it has not already been delivered. I also ask that you review CN Express’ handling of this shipment and your customer service responses, as they have not provided a real solution despite multiple contacts.
